Boxing

Dating all the way back to ancient Greece, boxing is an intense sport which requires extensive training and rigid discipline. Practicing boxing or taking boxing-based classes can help improve your cardiovascular health, your strength, your flexibility and your focus. A lot of gyms have punching bags and speed bags. Some gyms even have boxing rings for training proprioception (sense that indicates whether the body is moving with required effort and how parts of the body are located in relation to each other) and building strength. However, the most serious training happens at gyms that are specifically for boxing.
